urine is normally yellow.
Urine is yellow due to the presence of a pigment called urobilin. When urine is dilute,its colour becomes light due to the abundance of water. Dark yellow urine shows that the urine is concentrated which is because of dehydration.
your son's urine is yellow because he doesn't drink much water.
If you have a pale yellow urine to a darker shade means that you are well hydrated to less hydrated when urine becomes concentrated.
